About this model

Ever wondered if your 3D printer can print threads that aren't terrible? Now's your chance! Download a 16mm, 12mm or 10mm test runner sheet, load it up in your favorite slicer with the settings below and find out! And as usual, it wouldn't be a ThirtyThreeDown design if you couldn't throw it on your keychain as a keychain charm: snip the parts off the runner sheet, assemble and you're done! These are part of my quest to make the best possible 3D printed threads I could think of for functional parts and cosplay props. Find out more on my website! WARNING - The 12mm runner sheet's threads are not matching for some reason. I will upload a fixed version this week, I'm pulling the file in the meantime!
